bonjour

g ( 3) =  4

g (x) = 4 x/ 3

g (9) =  36/3 = 12

g ( - 6 ) = - 24/3 = - 8

Bonsoir

19 sest la fonction linéaire telle que g(3)=4

Calculer mentalement g(9) et (-6).

Fonction linéaire : y = ax

g(3) = 3a = 4

a = 4/3

Donc g(x) = 4x/3

g(9) = 4 * 9 / 3 = 4 * 3 = 12

g(-6) = 4 * (-6) / 3 = 4 * (-2) = (-8)
